JUSTIFYING DEVICE FOR COMPOSING -MACHINES.

SPECIFICATION forming part of Letters Patent No. 753,336, dated March 1,1904. v

' Application filed August 24, 1897.

.To all whom) it may concern.-

Be it known that I, JAMES A. WATSON, a citizen of theUnited States,residing at Washington, in the District of Columbia, have inventedcertain new in J ustifying Devices. for Composing Machines, of which thefollowing is a specification. I

The present invention relates to justifying mechanism for matrix-makingand other composing-machines. As illustrated in the drawings, it isapplied to matrix-making machines; but it will be understood thatcertain features of the invention are applicable to othercomposing-machines, such as those which 'cast or set type.

The object is to justify lines of composition by automatically anduniformly increasing or decreasing the normal word-spaces of the linesthe amount necessary to bring the lines to the standard length or'columnwidth.

The invention will be described in detail in connection with theaccompanying drawings, in which Figure 1 is a plan view ofjustifyingmechanism embodying my invention. Fig. 2 is asection on the line 2 2,Fig. 1. Fig. 3 is a plan view illustrating a modification; and Fig. 4 isa section on the line 4 4, Fig. 3.

The justifier requires to be set either manually or automatically priorto the final production of each line. As illustrated, it is adapted tobe set by keys and key-levers. It

is to be presumed that before setting the justi-' fier for any givenline the number of wordspaces in that line and aggregate width of theword-spaces necessary to justify have been calculated or, what ispractically the same n total variation space or amount to be added to orsubtracted from normal spaces has been calculated. "In the caseillustrated in the drawings I apply the justifier to a supplementalfeeding device, which produces a movement additional or supplemental tothat of the main feeding device.

In Figs. 1 and 2 A indicates a matrix-car-- riage which is connected bya rack 1 and pinion 2 with a ratchet-wheel 3, which is urged and usefulImprovements v consists of a right-and-left that the'number ofword-spaces and the Serial'No. 649,360. (No model.)

erated by a magnet 6. Any suitable feeding;

device may be substituted for that illustrated, such device beingmounted upon the slide 7. The parts 1 to 6, inclusive, and theirequivalents I shall designate as the .main feeding device B. The slide 7is moved by a supple.- mental feeding device C, which, as shown, screw8, one end of which operates on the threaded bearing 9 on the slide 7and the other end operates in a fixed bearing 10 upon the main frame.The screw is driven bypinion 11 and gear 12,. friction-wheel 13, thefriction-wheel 13 being connected to gear 12. The pawl is carried on anarm 15, which is connected by a link 16 to the justifyinglevers, to bepresently described. The pawl 14 engages the disk 13 frictionally. sothat the slightest movement of the pawl will be communicated to the diskand through it to the slide 7 and matrix-carriage A. r

The justifier proper consists, as shown ,in

and cooperating-pawl '14,

Figs. 1 and 2, of a dividing-lever D, a multiplying-lever M, two adaptedto be applied to said levers, r espectively, and two series of keys dmfor operating said fulcra, respectively. The dividinglever D is pivotedto a connecting-rod 17, which slides in a guide 18. The opposite end ofthe lever is normally drawn back by a spring 19 against an adjustablestop 20, and it is provided with an armature 21 adjacent to a magnet 22,by means of which it may be drawn forward agalnst a stop 23. The stops20 and 23 may be adjusted so that the movement of the dividing-lever atthe stops will be equal to the movement required to be given theconnecting-rod 16 in order to produce a unit movement of thematrix-carriage A.

The lever M and slide 17 are drawn to the right by a spring 24 against astop 25, andthe other end of lever M is drawn to the left by a spring'26 against an adjustable stop 27. The fulcra d are arranged along thelever D at'regular fractions of its effective length, which isthedistance between thestop 20 and pivot 28, the first fulcrum beingone-half of series of fulcra d m,
